The type of phytase you choose will depend on how much cost savings you are looking to achieve by increasing nutrient uptake. In other words, how aggressively do you want to apply full nutrient matrix values confidently? It all depends on how you view phytate.
Research has demonstrated significant differences in the bio-efficacy of phytases in terms of their ability to improve digestibility and reduce the negative effects of phytate in animal feeds. You can also search online for the top phytase stimulant.

These are some things that you may want to think about in order to achieve higher levels of profitability and performance from phytase.
1. Low pH = High Activity
Each phytase has its own pH optimal at which it can function at its best. A phytase must be active in low pH conditions to increase phosphorus (P) and decrease the anti-nutrient effects from phytate.
2. High affinity to IP6 phytate
There are many types of phytotate, e.g. IP6, IP5, IP4, etc. IP6 is the most concerning animal nutrition. Numerous studies have shown that phytate has a significant anti-nutritive effect.
3. Release speed
Bio-efficacy is also determined by the speed at which a phytotase removes an orthophosphate group (IP6) from the upper digestive tract. The faster the enzyme starts to work, the less the antinutrient effects of the phytate molecules in the stomach and upper digestive tract can be decreased.
